The forces of LSI are poised for a revolution in data processing. Fabrication capabilities are at the level of a microprocessor on a chip. Processor chips with 750 to 1,000 gates per chip in 4-bit and 8-bit data paths are in production in significant quantities, as are 1K-bit memory chips, with 4K-bit chips becoming available. What are the implications? In what directions will the technology and design advance? These were the questions studied in a workshop conducted by the Computer Society's Computer-Elements Committee last June in Vail, Colorado.
